Abstract (en)

The present invention relates to an internal combustion engine (11) having at least intake (22,23) port means cooperating with the combustion chamber (21) for delivering a charge to the combustion chamber (22). In particular, means cooperating with the intake port means (22,23) are provided for causing the intake charge delivered to the combustion chamber to assume a tumble motion rotating (t,t') about a tumble axis (x) that extends transversely to the cylinder bore (13) axis, which tumble axis (x) is disposed substantially at the centre of the combustion chamber volume (21) when the piston (15) is travelling at its maximum speed. <IMAGE>
